The correct statement regarding acrocyanosis is D) Acrocyanosis is cyanosis of the hands and feet, and is a normal finding in infants younger than 2 months of age who are cold.
Acrocyanosis is a condition characterized by a bluish discoloration of the hands and feet. This happens due to the constriction of blood vessels near the skin’s surface in response to cold temperatures or emotional stress. When blood vessels constrict, less oxygenated blood reaches the extremities, resulting in cyanosis.
Acrocyanosis is considered a normal finding in infants younger than 2 months of age. Their circulatory system is still immature, and their peripheral blood vessels are more sensitive to changes in temperature. Therefore, when exposed to cold, their hands and feet may appear bluish. As the body warms up, the normal circulation is restored, and the acrocyanosis resolves.
It is important to note that acrocyanosis in infants younger than 2 months of age who are cold is generally harmless and self-resolves. However, if the cyanosis is persistent even when the extremities are warm, or if there are other concerning symptoms, it is advisable to seek medical attention to rule out other possible underlying conditions.
The other options (A, B, and C) are incorrect:
A) Acrocyanosis is not a late finding of respiratory failure or shock. Cyanosis of the skin and mucous membranes can occur in these conditions, but it is not specific to acrocyanosis.
B) Acrocyanosis is not limited to newborns and typically resolves within 12 hours following birth. It can also occur in older infants and adults due to factors like cold exposure or stress.
C) Acrocyanosis is not a bluish discoloration of the chest, abdomen, and face. It specifically refers to cyanosis of the hands and feet. Cyanosis affecting the chest, abdomen, and face may indicate more severe perfusion problems and require immediate medical attention.
